(a) Notwithstanding any other provision of this part, no payment of extended duration benefits shall be made to any individual for any week or part of any week with respect to which he is entitled to receive unemployment compensation benefits as a result of participation by this state pursuant to the provision of any federal law providing for the payment of such benefits or as a result of the application in any other manner to this state of any federal law providing for the payment of such benefits.

(b) With respect to weeks commencing on or after November 29, 1970, this subdivision shall apply and subdivision (a) of this section shall not apply to benefits under the “Federal-State Extended Unemployment Compensation Act of 1970”.

(1) Notwithstanding any other provision of this part, if an individual would have rights to receive benefits under the federal act within an “extended benefit period” under the federal act, the director shall cancel such individual’s rights to extended duration benefits within that “extended benefit period”.

(2) A cancellation under this section does not affect extended duration benefits paid with respect to a week preceding such cancellation.

(3) Notwithstanding a cancellation under this section, an individual otherwise qualified for extended duration benefits during an “extended benefit period” under the federal act, may, upon the expiration of his “eligibility period” specified by the federal act, establish rights to, and be paid, extended duration benefits subject to the following conditions:

(A) If the individual has filed a primary claim in the “extended benefit period”, under the federal act, he may reestablish his extended duration benefit rights, if the extended duration period would not have expired.

(B) If the individual has not filed a primary claim in the “extended benefit period”, under the federal act, and he has claimed benefits pursuant to the federal act during an extended duration week in such “extended benefit period”, he may file a primary claim effective with that extended duration week, if the extended duration period would not have expired.

(C) If the individual has not filed a primary claim in the “extended benefit period”, under the federal act, and he has claimed benefits pursuant to the federal act but not during an extended duration week in such “extended benefit period”, he may file a primary claim in an extended duration week.

(D) The individual shall not be paid extended duration benefits for any week for which he receives federal benefits.

(4) An individual may be paid extended duration benefits with respect to a parent benefit year only to the extent that the total amount of such extended duration benefits and benefits paid under the federal act since the beginning of such parent benefit year does not exceed 13 times his weekly benefit amount or one-half of the maximum amount of normal benefits payable to him during that parent benefit year, whichever is the lesser.
